Advent Calendar- How to disable comments for WordPress pages in any theme

Usually you don’t need comments on pages. Unfortunately, WordPress doesn’t offer a separate option to leave comments on posts on and turn them off for pages. If your theme calls comments_template(); in its page.php and you don’t want to break automatic updates, you cannot just remove the function call, because it will be overwritten with the next update.

No problem. There’s an hook for that. It’s a filter called … wait for it … comments_template. We can change the path to the comments template here – if haven’t figured that out already. Let’s build a small plugin.

So, what do we do? We hook into comments_template(); and change the path. Our new path should point to an existing file without any HTML output. In this case, we use just our plugin file, because we know it exists and we control the output.

As you may have noticed our plugin file is included two times: First as a plugin, later as a replacement for comments.php. The function_exists() check prevents any You cannot redeclare … errors.

If you have access to your theme just change the page.php.
